Linear regression of projected plant area as output of the depth data pipeline vs. projected plant area obtained from the RGB data pipeline (ground truth). The regression line is colored black, while the angle bisector line is drawn two-dashed. Gray indicates confidence interval limits at α = 0.95. Adj R2 denotes the coefficient of determination adjusted according to Yin and Fan [27], while Pslope and Pinter represent p-values of the coefficients for the intercept and slope determined by simple T-test. MAE, MRE and RMSE indicate the mean absolute error, mean relative error and the root mean square error of projected plant area. Sampling (n) was formed out of 12 images from four different culture containers and 12 time points respectively (DAT 0–DAT 11)
